Benefits of technology

[0010] The major feature of the invention is the combination of the retractable arm and the biaxial hinge, so that the distance between the two speakers can be varied according to actual requirements. In addition, the speakers keep facing forward or a pre-determined direction, so the multimedia audio dock of the invention can be applied on portable electronic devices of various types and sizes, and is no longer restricted to a certain model. Moreover, the design of variable distance between two speakers enables the portable electronic device to be realized in a vertical or lateral arrangement based on the software settings. Hence the portable electronic device can fully utilize the setting of software to fulfill requirements for playing multimedia files or running application programs.

Problems solved by technology

The conventional speaker or dock for the portable electronic device is large sized and not convenient to be carried or to be kept somewhere, so that the audio output performance of the portable device is limited.

Embodiment Construction

[0019] The purpose, construction, features, and functions of the invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings.

[0020] Refer to FIGS. 1 to 4 for an embodiment of the multimedia audio dock of the invention. The multimedia audio dock includes two retractable arms 10, a biaxial hinge 20, and two speakers 30.

[0021] The retractable arm 10 is formed by a plurality of tubes in a sleeved-through manner. Each of the tubes can slide relative to each other to a location and then be fixed, so that the retractable arms are realized at a pre-determined length. In this embodiment, two tubes are provided in the each of the retractable arms, wherein the profile of the outer perimeter of one tube 10a is slightly smaller than the profile of the inner perimeter of the other tube 10b, so that they may be in a sleeved-through manner and slide relative to each other to change the length of the retractable arm...

Abstract

A multimedia audio dock is provided to support a portable electronic device so that the portable electronic device can stand on a plane. The multimedia audio dock includes two retractable arms formed by a plurality of sleeved-through tubes so that the length of the two retractable arms can be varied to a predetermined length. A biaxial hinge providing two rotational axes is connected to the two retractable arms, so that the two retractable arms may rotate relative to each other about two rotational axes. Two speakers provided respectively at the ends of the two retractable arms opposite to the ends connected to the biaxial hinge. The speakers receive the audio signals and output sound. And the electronic device is held between the two speakers moved by the two retractable arms, so that the portable electronic device can stand on the plane.

Description

PRIORITY STATEMENT [0001] This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 94211909 filed in Taiwan on Jul. 13, 2005, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of Invention [0003] The invention relates to an audio device, and in particular relates to a multimedia audio dock connected to a portable electronic device. [0004] 2. Related Art [0005] Presently, portable electronic devices such as personal digital assistants (PDA) or MP3 (MPEG Layer-3) players use earphones to provide audio output. Some models may be provided with miniature built-in speakers, but a single speaker can not provide stereo sound output, and the size is too small to output sufficient power, so that the volume of sound the speaker produces is too low to be heard clearly. Hence built-in speakers are useless in producing effective audio output. Generally, most of the user use earphones to prov...
